To aid who/rt lit 'HI/(Ll/ concern:

Be it known that 1, ANDREW RAICHE, a citizen of the United States, residing at Quincy, county of Norfolk, and State of Massachusetts, have invented an Improvement in Hook-Setting Machine, of which the following description, in connection with the accompanying drawings, is a specification, like letters on the drawings representing like arts.

p Prior to this invention in machines of this class it has been customary to supply a spindle with a hook while the spindle occupied its lowered position in line with an anvil, and thereafter the spindle has been raised to thrust the tubular shank of the hook through a hole previously punched in the stock, or the shank of the hook has been thrust through the stock, and in both these machines it has been customary to feed the stock by hand.

In'the form of machine wherein the holes for the shanks of the hooks are punched on a separate machine the stock is fed by hand, so that one after the other of the punched holes is passed over the shanks of the hooks. The other class of machine, where the shanks of the hooks have been forced through the stock, is employed only in connection with cheap work, where faults in the spacing of the hooks, due to inequality of feeding the stock by hand, are considered immaterial.

Herein I have, as I believe, for the first time constructed a device for securely holding a hook while its shank is passed through the stock, said device, while said shank is in the stock, being automatically moved laterally to effect the feeding of the stock.

In my improved machine it is possible to automatically insert and accurately space the hooks in the stock, and by automatically feeding the stock after setting each hook it becomes possible to set the outside of the neck of each hook parallel with the edge of the parts or flies of the shoe in which the hooks are set.

Figure 1, in side elevation, represents a hook-setting machine embod g'ing my present invention, the parts being in their inoperative positions or positions of rest. Fig. 2 is a through the stock, a part of the raceway, and a device for feeding the hooks one at a time into the hook-sustaining plate. Fig. 3 is a detail showing the hook-sustaining plate in its hook-receiving position. Fig. 4 is the front or left-hand elevation of the machine shown in Fig. 1. Fig. 5 is, a detail of the plunger and hook-sustaining plate detached from the machine. Fig. 6 is a detail showing part of the means employed for feeding the spindle and hooksustaining plate laterally when feeding the stock, and Fig. 7 shows part of the table-plate and an edge-gage' The framework of the machine is of suitable shape to sustain the working parts. One part of this framework sustains a work-table A, provided with a suitable edge-gage A which may be adjusted with relation to the front of the work-table and the point where the shanks a of the lacing-hooks a are thrust into the stock.

The upper part of the framework has suitable bearings B to sustain a rock-shaft B, having at its rear end a crank B provided with a crank-pin that is engaged by the upper end of a link B the lower end B of which is slotted to embrace the main drivingshaft B said lower end having projecting from one side thereof a suitable stu i B that enters the groove of a face-cam B, fast on said shaft. The Shaft B has at its front end a disk C, provided with a crank-pin C, that carries a slide-block 0 said slide-block entering a groove in a block C secured to the shank U of the anv.l D by meansof a suitable s'et-screw O and as said shaft is rocked the anv l is lowered and raised as required. The dotted circles, Fig. 4, above and below the crank-pin C show the positions occupied by the crank-pin as the shaft B is rocked. The shank C is free to slide in suitable bearings C, forming part of the framework, and said shank at its upper end has a hand-wheel C that may be turned to provide for the vertlcal adjustment of said shank and the anvil D at the end thereof,the said shank being threade i, as at C to engage threads of the block C said threads, coacting with the setscrew C affording absolute accuracy of adjustment and maintaining the adjustment to exactly the proper point with relation'to the a vice e as the latter is actuate .1

per eni to receive a pin 6 exten'ie i cured to the lower end of the shank C in any usual manner, an d in its lowest position during the setting of the shank of the hook in the stock the anvil is made to act upon the upper side of the stock supported on the work-table.

Fig. 1 shows the stock, supposei to be leather D, as resting on the work-table, and the stock is actecl upon at its upper side by a presser-foot D shown as angular in shape and connected by asultable clamoing-screw D with a block 1), secured to a slide-rod D by a suitable screw, said block and presserfoot being adjustable vertically to correspond with the thickness of the stock in which the hooks are being set. The presser-foot must be raised automatically from the stock after setting each hook, and to do this I have in the present instance shown presser-foot-lifting means comprising a link I), jointed to one end of the block D said link being in turn jointed with the end of a lever I), mounted on a fulcrum b carried by the framework.

The lever b has connected with it at b a link b that is jointed to the upper end of a rod b movable verticallyin suitable bearings b, said rod having at its lower end a roller 6, that is acted upon by the periphery of a cam b to raise said IOfl and the lever when the presser-foot is to be lifted automatically when the stock is to be released that it may be fed.

The ro:l has an attached collar b", that sustains the lower end of a spring 19 said spring acting normally to keep the presserfoot yiel lingly upon the face of the stock. This presser-foot has to be raised prior to inserting the stock and before starting the machine in operation, and to do this I employ a lever I2 ")referably forked at one end to embrace the rod and act upon the collar b", said lever having its fulcrum at 6 and having a backward extension with which is connected a link I), in turn attached to some suitable foot-trea dle.

The main shaft If is provided with a set of cams E, F, G, and H. The cam E, represented as a face-cam, acts on a roller or other stul e at the lower end of a lever having its fulcrum at 0 said lever being slotte'l at its up- 1 from the hoolcsup'olying fievice,reoresentel as a sliding bar 0, aiaptel to be reciprocatel in a suitable guideway 6 sustained. by the framework beh, ni a cover-plate c. of the hook sustaining device is adapted when thrust to the left or forwardly in Figs. 1 and 2 to meet the outside of the neck of the hook and move the same off from a shelf or projection 6 which is stationary with relation to the end of the usual raceway e the heads of the hooks as theyleave the raceway being sustainel by said projection e in the path of movement of the hook-supplying deby the lever e.

The cam G rotates inside and contacts with the parallel faces of a yoke G, shown as The front eni guided by uprights G erected on the base of the framework, and raises and lowers said yoke for purposes to be hereinafter described.

The yoke Ur has a plane face 2 represented as occupying a position in a horizontal plane, and said face sustains the lower end of a spindle 4, the latter being hollow for most of its length and being threaded at its upper end to receive a threaded boss 5 of the head 6 of the spindle. The head 6 at its upper side has a recess g to receive from the raceway the hook to be set, and said head is grooved (see Fig. 2) to constitute a guideway for the reception and guidance of the shank g of the hook-sustaining plate 9 the shape of which is best shown in Figs. 2 and 3.

The sustaining-plate has a shoulder '8, against which strikes the inner side of the neck of the hook, and in line with said shoulder there is a notch 10, that when the plate is moved forwardly from the position, Fig. 3, into its operative position, Fig. 2, embraces the neck of the hook.

The setting-plate derives its motion from an elbow-lever g pivoted at 12 and having a stud 9 that enters a slot (see Fig. 5) in the upper end of a rod 9, having a stud 13, said rod entering the hollow spindle, the stud 13 extending outwardly through a slot 14 in the spindle 4, where it receives a roller g.

The rod 9 in Fig. 5 is represented as surrounded by a spiral spring h, the lower end of which rests on a shoulder h of said rod, and said spring acts normally to depress the rod and maintain the hook-sustaining plate in its operative position with the roller g on the actuator f so that when said actuator constituting part of a parallel motion is ralsed, as will be described, the sustaining-plate will be withdrawn from the throat of the hook.

Each hook is taken by the hook-presenting device from the raceway shown in Fig. 2 and is transferred from the raceway to the hooksustaining plate when the latter is in the position shown in Fig. 3, the throat of the hook-sustaining-plate being stop ed by contact with the shoulder 8 of said pl zlte occupying, as represented in said figure, its hookreceiving position in or with relation to the spindle, and thereafter the hook-sustaining plate g is moved forwardly in the throat of the hook until (see Fig. 2) the notch of said plate embraces the neck of the hook, as represented in Fig. 2, said plate thereafter holding the hook firmly seated during the operation of expanding the shank of the hook in the stock and while the stock is being fed after the shank of the hook has been upset in the stock, the plate during the feeding operation of the stock occupying a position in the throat of the hook.

The yoke G has a stud f, upon which is mounted an elbow-lever f, the lower arm of which is provided with a roller f that is normally maintained in contact with the pe- ITO riphery' of the irregular cam H through the spring h. The upper end of the longer end of the lever f is jointed atf to an actuator f 4 in turn jointed at f on the upper end of a link f, the lower end of which is free to turn about a stud f carried by the yoke G.

It will be understood in the revolution of the cam-shaft that the cam H, acting through the roller f will turn the elbow-lever f and raise and lower the actuator f the upper side of the latter being maintained in the same horizontal plane, notwithstanding it is raised and lowered, this being effected through the link f. The upper side of the actuator sustains the roller 9.

The cam H is so shaped with relation to cam G that for part of the movement of the yoke G the actuator f is moved in unison with the yoke, as when the yoke is rising and while the s indle is being moved, as will be described, aterally along the actuator for feeding the stock; but at the 0nd of said stock-feeding stroke and just before the slide begins to descend the actuator is raised by a part of the cam H to effect the withdrawal of the hook-sustaining plate from the throat of the hook, the latter having been set in the stock then sustained on the table-plate.

The cam F or feed-actuator rotates between the forked ends of a lever F or device interposed between said feed-actuator and the block F said lever being pivoted on a stud F sustained in the back of said block.

F adapted to be slid horizontally with its spindle, which is guided therein as the spindle is moved vertically, said block having at its rear side a hole to receive a guide-rod F, that is free to slide through suitable ears F of the framework.

The lever F is slotted at m to receive a fulcrum m that is made adjustable vertically in the framework of the machine by movement of the forked end m of a feed-controller m having its fulcrum at m. Said feed-controller has a pointer m (see Fig. 4,) that cooperates with a series of lines of an index m formed on an upright m suitably secured to the framework. The index-lines m indicate the positions that the feed-controller must occupy in order to secure a certain definite spacing of the hooks for different-sized shoes.

In operation let it be assumed, reviewing Figs. 1 and 4, that the spindle has been lowered and that when in its extreme lowered position the hooksustaining plate was slightly retracted by slightly lifting the actuator and that the hook-presenting device has acted and has transferred a hook from the raceway into the recess 9 of the head of the spindle, as represented in Fig. 3, and that the actuator has-been then started and moved sufficiently to enable the spring h to move the hook-sustaining plate to enter the throat of the hook. In this condition, Fig. l, the

spindle starts on its rising movement. After the hook-setting plate has been moved forwardly to engage the throat of and lock the hook in fixed position with relation to the spindle the spindle inthe continued motion of the machine is raised from the position shown in full lines, Fig. 4, into the dottedline position, and the shank of the hook is passed through the stock on the work-table, held thereon by the action of the presserfoot on the upper side of the stock. Prior to the shank of the hook being passed through the stock the anvil is caused to descend upon the surface of the stock and remains in its lowered position while the shank of the hook is penetrating the stock, the hollow shank of the hook contacting with the surface of the anvil being turned outwardly and flanged, thus setting the shank of the hook firmly in the stock. This done, the anvil immediately retires from the stock, the presser-foot is raised, and the cam F moves the block F horizontally to the left, Fig. 4, taking with it the devices carried thereby and holding the hook, among which is the hook-sustainingplate, yet in engagement with the hook, the shank of which has'been set in the stock and the stock is fed for just the proper distance, that depending upon the size of the shoe in which the hooks are being set, as indicated by the position of the feed-controller m".

The block F having been moved to feed the stock for exactly the proper distance, the presser-foot descends upon the stock on the feed-table and immediately thereafter the actuator is raised sufliciently by the cam H with relation to the upper end of the yoke G to raise the rod 9 and withdraw the hooksustaining plate from the throat of the hook preparatory to the descent of the settingspindle which is effected through the action of cam G. The yoke G is made to descend by the cam H after the withdrawal of the hook-sustaining plate from the throat of the hook and after thestock has been fed. As

the yoke arrives in its lowest position, with the hook-sustaining plate in position to be again supplied with a hook from the raceway, the spring h acts to move the hook-sustainling plate forwardly into the throat of the hoo r.

As soon as the work has been fed into posi-. tionwith relation to the spindle the hooksustaining plate is moved forward quickly, as stated, to engage, lock, and retain the hook in setting position while the operations just described are repeated,
